Installation Tips:
-
All adhesive gaskets have a limited shelf life. These products must be used within 6 months of purchase and must be stored between 50ºF and 100ºF.
-
Thoroughly clean the frame with the enclosed cleansing towelette to remove grease, dust or cleanser build-up. Before installation, wait for frame surface to completely dry (evaporate). Some hospital environments have wax or anti-bacterial cleanser build-up. As an alternative or substitute cleanser, use isopropyl (rubbing) alcohol. Note: Mineral spirits or other petroleum based cleaning products should NOT be used.
-
If frames are too cold (below 50ºF) or too hot (above 100ºF) adhesion may be impaired.
-
Installation should take place after construction is completed, flooring is installed and final cleaning is completed.
-
Paint on frame must be cured for at least 5-7 days. Paint cannot be wet under dry surface when gaskets are pressed on. Avoid quick-dry primers, which leave a powdery surface preventing sufficient adhesion. When applying to a wood frame, the surface must be non-porous and sealed. Follow standard industry guidelines on sealed wood frames and/or rough surface before applying. Note: Anti-bacterial, anti-fungal or silicone additives in paint may inhibit adhesion.
-
Do NOT stretch material. Product can retract or shrink if stretched.
-
Use very firm, perpendicular pressure when applying. Use wallpaper seam roller to reinforce adhesion after applying.
-
Do not stretch material when using seam roller. Run roller with up and down motions.
-
Double check adhesion after 2-3 hours before leaving job overnight.
-
If gaskets separate from the frame, press again with firm pressure in place. If adhesive strip is exposed, airborne dust may impede adhesion. Replacement may be necessary.
-
Application at header can be awkward due to overhead condition. Be sure to apply enough pressure.
-
Adhesion takes delayed set. Immediate removal and resetting can be done if error occurs in initial placement. DO NOT reset after one hour. Full set is reached in 24 hours.
